Antifungal assay-guided isolation of the ethanol extract of the aerial parts of Clematis tangutica yielded two novel triterpene saponins. Their structures were determined to be 3-O-a-L-arabinopyranosyl hederagenin 28...
Two new triterpenoid glycosides, hederagenin-3-O-b-D-xylopyranoside (1), dodecandral 3-O-b-D-xylopyranoside(2), were isolated from Elsholtzia bodinieri Vant. The structures of 1 and 2 were established by spectroscopi...
Two new triterpenoid saponins, tanguticoside A and B were isolated from aerial part of Clematis tangutica. Their structures were elucidated as 3-O-beta-D-glucopyranosyl hederagenin 28 O-alpha-L-rhamnopyranosyl- (1-->4...
